Yes, I know you're weird but that's not the point. You tell someone up front "13 min" and they pass you by. You tell them NOTHING and they start reading. They give the piece a chance. If they get hooked they get hooked, if not not. That number has the effect of turning them off before the writer has a chance of turning them on. It might be 3 or 4 min. Some people are that short-tempered. And Medium is feeding into that. It isn't good for people who write long. Just like "reading time" isn't good for people who write short, like poets. This is one more way Medium is flatenning the reading curve to some imagined perfect "content" middle.
